3 Claims.

The present invention relates to an improved lock for any form of double hung window sashes, namely upper and lower sashes, where the lower sash might be partially open, thereby preventing ingress of a burglar from the exterior.

The invention has for its purpose to provide a plate of any suitable metal, steel or brass, preferably the former, with its opposite ends bent V angularly, the two angularly bent ends provided with caps of any suitable material preferably rubber, one side of each of which being corrugated, one cap covered end to be inserted between the upper rail of the lower sash and one of the vertical rails of the upper sash, said inserted end being so angularly formed as to spread the two sashes apart and bind them together, while the upper angular end of the plate has its cap corrugated on one face and sufficiently widened to bear against the bead stop of the window frame, thereby locking the upper and lower sashes so that neither one of them can be moved, and hence preventing ingress from the exterior. In applying the plate or device a lever action is applied on the upper rail of the lower sash, as a result of the weight or load of the upper sash, there being a fulcrum and pressure on the bead stop as force to prevent displacement of either sash.

It is to be understood that the particulars herein given are in no way limitative, and that while still keeping within the scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and combintaion of parts to be hereinafter set forth, shown in the drawing and claimed.

In the drawing:--

Figure 1 is a view in perspective of a portion of the side rail of a window frame, showing the upper and lower sashes partly opened and illustrating the locking device as applied.

Figure 2 is an edge view of the locking device.

Figure 3 is a view in elevation of a locking device to be used at one side of the sashes.

Figure 4 is a View in elevation of a locking device for the opposite side of the sashes.

Referring to the drawing 1 identifies a locking device for upper and lower double hung sashes, one to be applied at both sides of the window sashes, said device comprising a plate constructed of any suitable metal either steel or brass, preferably the former, the body 2 of the plate assuming a diagonal position between the side rail of the upper sash and the bead stop of the window frame. The body of the plate has upper and lower angular ends 3 and 4. The upper end 3 extends at an obtuse angle to the body 2 of the device in parallelism to the bead stop 5 of the window frame. This obtuse angle end has a cap or covering 6 of any suitable material preferably rubber, and its face 7 is corrugated for frictional engagement with one face of the bead stop, creating a binding action. The lower angle end 4 of the body of the device comprises two portions 8 and 9 at an obtuse angle to each other, while the portion 8 is at an obtuse angle to the body of the locking device. This lower end of the device also has a covering 10 of any suitable material such as rubber, and the faces 11 and 12 (which correspond to the portions 8 and 9 of the lower end of the device) of the cap or covering have corrugations 13, which when the lower end of the device is inserted between the upper rail of the lower sash and the side rail of the upper sash bind on the surfaces of such parts and insure friction to hold the device in position shown in Figure 1, and in such wise as to create a lever action of the body 2 of the device toward one face of the bead stop, and thereby bind the two sashes in partial open positions.

Referring to Figure 3 and 4 it will be noted that the bodies of the two locking devices have lateral ofiset portions 14, in which case a looking device may be used at each side of the window, the oifset portions 14 allowing the upper end of each device to overlie one face of the bead stop. The upper end of each locking device. is provided with a pin or lug 15 struck up from the metal and protruding through the cover or cap of rubber and adapted to engage in the bead stop of the window frame to insure holding the locking device in place and thereby prevent movement of either of the sashes.

The invention having been set forth, what is claimed is:

1. As an article of manufacture, a locking device for upper and lower hung window sashes comprising a body plate having upper and lower angular terminals, the lower terminal to be inserted between the upper rail of the lower sash I00 and the side rail of the upper sash, thereby holding the body of the device in a diagonal position and creating a lever action toward one face of the bead stop, whereby the upper angular end may bear against a face of the bead stop, and means on the upper and lower ends of the body plate of the device for creating binding friction, thereby locking the upper and lower sashes in partial open position.

2. As an article of manufacture, a locking device for upper and lower hung window sashes comprising a body plate having upper and lower angular terminals, the lower terminal to be inserted between the upper rail of the lower sash and the side rail of the upper sash, thereby holding the body of the device in a diagonal position and creating a lever action toward one face of the beadstop, whereby thecupper angular end may bear against a face of the 'beadsto'p, and means on the upper and lower ends of the body plate of the device for creating binding friction, thereby locking the upper and lower sashes in partial open position, the upper angular terminal being oifset in a direction toward the side of the window frame whereby the upper angular terminal may engage with one face of the bead stop, the lower angular terminal, comprising two parts at an obtuse angle to each other, -acting to force the adjacent parts of the upper and lower sashes apart, and tending to bind them in the guides'of the window frame.

3. As an article of manufacture, a locking de-' vice for upper and lower hung window sashes comprising a body plate having upper and lower angular terminals, the lower terminal to be inserted between the upper rail of the lower sash and the side rail of the upper sash, thereby holding the body of the device in a diagonal position and creating a lever action toward one face of the bead stop, whereby the upper angular end may bear against a face of the bead stop, and means on the upper and lower ends of the body plate of the device for creating binding friction, thereby locking the upper and lower sashes in partial oped-position, and a pointed lug struck up from the upper end of the body plate to engage in the bead stop, thereby preventing displacement of the body plate.
